[0002]

2. Description of the Related Art In sanitary tampon, a string for withdrawal is generally attached to the rear end of the tampon body. It is known to use, for example, a water-repellent treated cotton thread or a cord made of a thermoplastic resin as the pull-out string. See also Kaikai 7
No. 22726 discloses that a pull-out string is made of a hydrophobic tubular material made of a thermoplastic resin.

However, all of these drawer strings are
At the time of taking out the tampon, the position of the tip of the tampon is often not known, which makes it difficult to take out the tampon. In some cases, the tampon was forgotten to be taken out.

[0004] Therefore, an object of the present invention is to provide a tampon in which the drawstring can be easily handled.

[0005]

According to the present invention, in a tampon in which a withdrawing cord extends from the rear end of a tampon body, the tip of the cord is made to have a color different from that of the other portion of the cord. The object has been achieved by providing tampons colored in different colors.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described based on its preferred embodiments with reference to the drawings. FIG. 1 shows a perspective view of an embodiment of the tampon of the present invention.
The tampon 1 of the present embodiment has a cylindrical shape,
It has a tampon body 2 having a substantially uniform thickness. The tampon main body 2 has a substantially hemispherical tip portion 3 located at the tip in the insertion direction, a rear end portion 4 located at the rear end in the insertion direction,
And an intermediate portion 5 located between the front end portion 3 and the rear end portion 4. A pull-out string 6 extends from the rear end portion 4. The front end portion 3, the rear end portion 4, and the intermediate portion 5 are integrated.

The tampon body 2 is made of a water absorbing material. As the water absorbent material, highly absorbent cotton fibers such as degreased cotton fibers, rayon fibers or a mixture thereof are used. These fibers are
From the viewpoint of liquid absorption performance, the fineness is preferably about 1 to 5 denier. The fiber length is preferably 20 mm or more, particularly 30 mm or more from the viewpoint of preventing the fibers from falling off. In addition, a small amount of hydrophobic fibers may be included as a constituent material of the tampon body 2.

The withdrawal cord 6 is composed of, for example, a water-repellent cotton thread or a cord made of a thermoplastic resin. A weight portion 7 containing a material different from the constituent material of the string 6 is provided at the tip of the withdrawing string 6. The weight portion 7 has a weight per unit length,
It is heavier than the weight per unit length of other parts in. By providing the weight portion 7, the leading end of the withdrawal cord 6 becomes heavy and the leading end of the withdrawal cord 6 hangs down when the tampon 1 is taken out.
As a result, it becomes easier to find the pull-out string 6 itself, and especially the tip end thereof. In addition, since the leading end of the withdrawal cord 6 hangs down, forgetting to take out the tampon is prevented. From these points of view, it is preferable that the weight per unit length of the weight portion 7 is 3 times or more heavier than the weight of the unit length value of the other portion of the take-out portion 6.

When the pull-out string 6 is made of water repellent cotton yarn, the weight portion 7 is formed by coating the tip end portion of the cotton yarn with a thermoplastic resin, or It is preferable that a thermoplastic resin molded into a predetermined shape is attached to the tip of the cotton thread. As a result, a water-repellent effect is imparted to the tip portion of the withdrawal cord 6, and the tip portion is less likely to be contaminated with menstrual blood. When the pull-out string 6 is made of a cord made of a thermoplastic resin, the tip end portion of the cord is made of a thermoplastic resin different from the thermoplastic resin for the same reason. Is more preferable.

The weight portion 7 has a diameter slightly larger than the diameters of the other portions of the pull-out cord 6.
As a result, the tip portion of the pull-out string 6 can be more easily found.

The length of the weight portion 7 is 5 to 20% of the length of the pull-out string 6 extending from the rear end of the tampon, and particularly 8
It is preferable that it is -15% from the viewpoint of handleability of the withdrawal cord 6 in terms of economy. The length of the withdrawal cord 6 itself can be generally about 80 to 150 mm.

It is preferable that the weight portion 7 is colored in a color different from the color of the portion other than the weight portion 7 in the pullout cord 6 because the tip of the pullout cord 6 can be more easily found. To color the weight portion 7, the weight portion may be formed using a thermoplastic resin colored in a predetermined color.

The portion of the pull-out cord 6 from the substantially central portion to the weight portion 7 has a different color from the color of the weight portion 7 and the color of the cord 6 near the rear end of the tampon body. It is colored. That is, the pull-out string 6 is divided into two different colors from the substantially central portion to the tip portion. As a result, when the tampon 1 is inserted into the vaginal cavity, the extent to which the tampon 1 has been inserted can be easily known from the color of the withdrawal string 6, and inappropriate insertion of the tampon 1 can be effectively prevented.

The tampon 1 of this embodiment can be manufactured, for example, as follows. First, as shown in FIG.
A plurality of substantially square sheet materials 8 made of a water-absorbent material are stacked and prepared. A pull-out string 6 is attached to the central portion of the sheet material 8. As shown in FIG. 3, the pull-out string 6 is folded in two so that a loop 6a is formed in the center thereof, and two free ends are directed from the lower surface 8a side of the sheet material 8 toward the upper surface 8b side. The sheet material 8 is penetrated and pulled out to the upper surface 8b side, and then two free ends pulled out to the upper surface 8b side are penetrated from the upper surface 8b side to the lower surface 8a side to be drawn to the lower surface 8a side of the sheet material 8 and looped. The sheet material 8 is bound by passing through the inside of 6a.

With the pull-out cord 6 bound to the sheet material 8, a known compression molding device is used, and the pull-out cord 6 is passed through the compression molding device to bond the pull-out cord 6. The sheet material 8 is narrowed down starting from the attached position and compression-molded into a cylindrical shape to obtain the tampon 1 shown in FIG.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the colored weight portion 7 is provided at the front end portion of the drawer string 6, but instead of this, as shown in FIG. 4, the weight portion 7 is provided at the front end portion of the drawer string 6. It is also possible to provide only coloring without providing. Furthermore, from the approximate center to the tip of the drawstring 6 is not divided into two colors,
As shown in FIG. 5, only the tip portion of the withdrawal cord 6 may be colored with a color different from the color of the cord 6 other than the tip portion.

Further, in the above-described embodiment, the portion of the withdrawing cord 6 from the substantially central portion to the weight portion 7 is different from the color of the weight portion 7 and the color of the cord 6 near the rear end portion of the tampon body. However, instead of this, as shown in FIG. 6, the portion from the substantially central portion of the draw-out string 6 to the weight portion 7 may not be colored. In this case, the weight portion 7 may be colored or may not be colored.

Further, the pull-out cord 6 may be painted in three or more colors from the tip end portion thereof toward the rear end portion of the tampon body.

Further, the tampon of this embodiment may be directly inserted into the vaginal cavity, or may be used together with an applicator to further facilitate the insertion operation.

[0021]

According to the tampon of the present invention, the handleability of the withdrawal cord is improved, and the withdrawal cord itself can be easily found during the removal operation of the tampon, and particularly the tip thereof can be easily found. It also prevents forgetting to remove the tampon.
